Influence of Sample Temperature on Reflectance Photometry and Electrochemical Glucometer Measurements

Abstract
OBJECTIVE: A study was conducted to determine the influence of sample temperature on manual reflectance photometers, automatic reflectance photometers, and electrochemical glucometers. RESEARCH DESIGN AND METHODS: Aqueous and blood-based control solutions were tested at temperatures ranging from 25 to 44°C. With the Accu-Chek 3, One Touch, and Satellite G glucometers, multiple glucose determinations were performed on each sample. RESULTS: The results indicate that the manual reflectance photometry glucometer is prominently influenced by variation in sample temperature. The effect of sample temperature is greatest at high glucose levels. CONCLUSIONS: Caution may be required in the interpretation of manual reflectance photometry glucometer measurements in febrile or hypothermic diabetic patients.
